Ac- cording to the invention, the required hydrogenation of the mono- and diolefms and the hydrodesulfurization of the organic sulfur compounds contained in the feed stream are carried out step by step under process conditions optimized in each case. Furthermore, the inlet temperature into the respective reaction zone is controlled such that overheating of the feedstocks is avoided, which other- wise leads to undesired coke deposits, cloggings and the accelerated deactivation of the catalysts used.
